Abstract

L'invention concerne un stator (1) comprenant un cadre de stator (10), un noyau de stator (20) et un ressort (30, 40, 50). Le noyau de stator (20) comprend à son tour au moins une lamelle (22) dotée d'une fente en queue d'aronde (24). Une barre de calage (12) est connectée au cadre de stator (10) et présente une queue d'aronde (14) destinée à être insérée dans la fente (24). Le ressort (30, 40, 50) est couplé entre une partie de la lamelle (22) et de la queue d'aronde (14) afin d'offrir un chemin de mise à la terre électrique entre le noyau de stator (20) et le cadre de stator (10). Le ressort (30) comprend un ressort à lames (32) présentant des première et seconde extrémités (32b, 32c) entrant en contact avec la queue d'aronde (14) et une partie centrale (32a). Cette dernière est connectée à une partie de base (37) qui entre en contact avec la lamelle (32). Selon une variante, le ressort (40, 50) comporte une partie de base (42, 52) entrant en contact avec la lamelle (22) et des broches (44, 54) qui font saillie de la partie de base (42, 52) et entrent en contact avec la queue d'aronde (14).
